FIG 4. 57-year-old woman with cerebral metastasis.
A—B, On T2-weighted fast spin-echo (A)(6000/128/1/6) and enhanced T1-weighted spin-echo images (B) (600/14/2/6) the differential diagnosis between metastasis and abscess is impossible.
C—D, Diffusion-weighted ("z" sensitizing direction) multishot echo-planar image (800/123/5/6) (C) and corresponding ADC map (D) show central hypointensity on diffusion-weighted image and hyperintensity on ADC map consistent with diagnosis of tumor.
